Provide version of struct efi_mem_desc in efi_get_memory_map(). EFI_BOOT_SERVICES.GetMemoryMap() in UEFI specification v2.6 defines memory descriptor version to 1. Linux kernel also expects descriptor version to be 1 and prints following warning during boot if its not: Unexpected EFI_MEMORY_DESCRIPTOR version 0 Signed-off-by: Mian Yousaf Kaukab <yousaf.kaukab@gmail.com> --- Resending the patch as previous attempt was blocked for some reason. include/efi.h | 2 ++ lib/efi_loader/efi_memory.c | 3 +++ 2 files changed, 5 insertions(+)
